[The following may be compared with this page that I posted five years ago: https://vellaunos.ca/2021/03/24/the-movements-and-expansions-of-indo-european-language-groups/ ]
The seven maps below are an attempt at briefly showing the movements of the various Indo-European groups in prehistory. Archaeological cultures associated with some Indo-European groups are shown in italics. Non-Indo-European groups are also indicated in CAPITALS along with some of their archaeological cultures in ITALIC CAPITALS.

Map 1 – 6000 BC
The Pre-Proto-Indo-Europeans lived in the forest zone east of the Ural Mountains. At some time before 5000 BC, part of this population migrated westwards through the Urals into the forest zone of what is now eastern Russia, this being the Proto-Indo-Europeans. These movements may have been precipitated by westward movements of Uralic peoples from the east. During this period, Anatolian Farmers (usually called “Early European Farmers”) begin to colonize southeastern Europe, eventually producing the Starcevo-Koros-Cris Culture [c6200 to c4500 BCE] of the central Balkans.

Map 2 – 5000 BC
The Proto-Indo-Europeans split into two dialect areas. The North Indo-Europeans expand westwards through the forest zone towards the Baltic Sea. Meanwhile, the South Indo-Europeans venture southwards into the steppe zone along the Volga River [Samara Culture c5000 BCE]. The South Indo-Europeans contact the Caucasians of this area, leading to admixture as well as the acquisition of agriculture. By this time, the Anatolian Farmer culture called the Linear Pottery Culture [c5500 to c4500 BCE] has developed from Starcevo and expanded through central Europe up to what is now eastern France, while the Anatolian Farmer Vinca Culture [c5400 to c4500 BCE] replaces the Starcevo Culture in the Central Balkans.

Map 3 – 4000 BC
The North Indo-Europeans inhabit the forest zone from the fringes of the Baltic to the Urals, maintaining a hunter-gatherer existence. Their main culture is the Comb Ceramic (or Pit-Comb Ware) Culture [c4200 to c2000 BCE]. The South Indo-Europeans expand westwards across the Pontic Steppe. Their cultures include the Khvalynsk Cuture [c4900 to c3500 BCE] and Repin Culture [c3900 to c3300 BCE]. During this period, the Anatolian Farmer culture called Cucuteni-Trypillia [c5800 to c3000 BCE] expands into the western part of the Pontic Steppe, while the Funnelbeaker Culture [c4300 to c2800 BCE] expands throughout northern Europe.

Map 4 – 3000 BC
The North Indo-Europeans split into two dialect groups: a western group which is the beginning of Balto-Slavic and an eastern group which is the beginning of Indo-Iranian (Volosovo Culture). The South Indo-Europeans have expanded to the foothills of the Carpathians, their culture being the Yamnaya Culture [c3300 to c2600 BCE]. Part of this population has migrated eastwards into the Altai region where the Afanasievo Culture [c3300 to c2500 BCE] eventually arises, this being considered to be the Tocharians. A group of Caucasians between the Yamnaya Culture and the Maykop Culture [c3700 to c3000 BCE] becomes Indo-Europeanized. Their culture is the Novotitarovskaya Culture [c3300 to c2700 BCE] and they are the beginning of the Gutians (who are usually misnamed the Anatolians). The Anatolian Farmer cultures of this period include the Globular Amphora Culture [c3400 to c2800 BCE] of northeastern Europe and the Baden Culture [c3600 to c2700 BCE] of the northern Balkans.

Map 5 – 2500 BC
The Corded Ware cultural complex [c3000 to c2350 BCE] spreads among the North Indo-Europeans, the Fatyanovo [c2900 to c2050 BCE] derivative of this developing among the Indo-Iranians. A mixture of South Indo-Europeans and Indo-Iranians in the Volga region produces the Poltavka Culture [c2800 to c2100 BCE], this being the original Greco-Phyrgian culture. The remaining South Indo-Europeans on the Pontic Steppe produce the Catacomb Culture [2500 to 1950 BCE]. The western part of the South Indo-Europeans has migrated into Central Europe via the Danube River, these being the earliest Celtic peoples. The Indo-Europoid Gutians have migrated to the Zagros Mountains via the north slope of the Caucasus Mountains and the west coast of the Caspian Sea.

Map 6 – 2000 BC
A part of the Indo-Iranians migrates eastwards across the Volga toward Central Asia, producing the Sintashta Culture [c2200 to c1900 BCE]. Those remaining in eastern Russia become the Thraco-Cimmerians of the Abashevo Culture [c2200 to c1850 BCE] (eventually the Srubnaya Culture on the Pontic Steppe [c1900 to c1200 BCE]). The Greco-Phrygian group migrates westwards onto the Pontic Steppe, their culture being the Multi-Cordoned Ware Culture [c2200 to c1750 BCE]. The South Indo-Europeans of the Pontic Steppe Catacomb Culture migrate westwards in two ways: one group migrates into the Hungarian region via the Danube River, this being the beginning of the Italic group; the other group migrates north of the Carpathians up to northern Europe, mixing with Baltic peoples along the way, this being the beginning of the Germanic group. Celtoid offshoots of the Celts have established themselves in the Atlantic regions (Armorican Tumulus Culture [c2200 to c1400 BCE], Wessex Culture [c2000 to c1400 BCE]). The Indo-Europoid Gutians have conquered and occupied Akkad for perhaps a century [c2200 to c2100 BCE], eventually being defeated and expelled, and ultimately ending up in Anatolia, becoming the Hittites, Lydians, etc (eventual Hittite retaliation on Babylon by Mursili I in 1595 BCE).

Map 7 – 1500 BC
The Indo-Iranians of the Andronovo Culture [c2000 to c1150 BCE] expand throughout Central Asia, eventually reaching modern Iran and northern India. The Thraco-Cimmerians of the Srubnaya Culture [c1900 to c1200 BCE] occupy the Pontic Steppe, displacing the Greco-Phrygians. These migrate into the eastern Balkans, a group of these invading and conquering the Helladic peoples of Greece, thereby producing the Mycenean Culture [c1750 to c1050 BCE]. The Germanic peoples of the Nordic Bronze Age [c1700 to c500 BCE] expand northwards into Scandinavia. The Italic peoples are established in the Pannonian Plain. The Celtic peoples of the Tumulus Culture [c1600 to c1200 BCE] are established in Central Europe, while the Celtoid peoples occupy the Atlantic periphery of northwestern Europe (north-western France, Great Britain, Ireland). The Indo-Europoid Gutians are established in Anatolia, one group of them forming the important Hittite Empire [c1650 to c1180 BCE].
